: If the stream list has too many entries to fit into the pane, the pane contents can be scrolled using the mouse wheel.

15.1.3 The stream list

If the right-hand pane (the streams list) is selected, the keys perform the following actions:

Move to the previous stream.

Move to the next stream.

+

Extend the selection to the previous stream

+

Extend the selection to the next stream

Open a new WaveViewwindow on the currently-selected streams.

Remove the currently-selected streams, and clear their data from the stream buffer.

Note: Deleting an active stream when recording is enabled has the side-effect of flushing any buffered data to disk. The stream will reappear as soon as the next packet is received.

: If the source tree has too many entries to fit into the pane, the pane contents can be scrolled using the mouse wheel.

15.2 WaveView windows

Most of the functions of WaveView windows can be accessed by a keystroke, a mouse movement or the combination of the two. This is particularly useful if you have removed the window decoration with the No Caption menu option.

15.2.1 Shortcuts for all streams

or

Increase the amplitude scale (zoom in vertically)

or

Decrease the amplitude scale (zoom out vertically)

“Roll up” the current entry

“Unroll” the current entry

or+

Increase the time scale (zoom in horizontally)

or+

Decrease the time scale (zoom out horizontally)

+

Set all scales to unity (i.e. display all amplitudes in counts)

Enter or leave "pause" mode (stop or start scrolling)

+

Scroll forwards in time when in pause mode

+

Scroll backwards in time when in pause mode

+

Create a duplicate window as an exact copy of the current WaveView window, with all settings the same

Null the offsets of all unlocked streams in the WaveViewwindow, so that the mean value of each is centred vertically in its respective lane

+

Toggle the spectrogram of all streams on or off

+

Increase the colour brightness of all spectrograms

+

Decrease the colour brightness of all spectrograms

Toggle the display of "lane lines" on or off

Toggle “overlay mode” on or off. In “overlay mode” all streams are drawn in the centre of the window, rather than having separate lanes. See also the following two entries

Restore standard axis spacing (see section 6.1.8). If standard spacing is already in force, this will recompute the display cache and redraw the contents of the WaveView window, cancelling any selection

Overlay streams

Space stream axes according to the instrument's depth. The calvals must contain a depth= entry for every stream in the window

If calvals contains position entries for every stream in the current window, this key will space the stream axes according to the distance from a set point, specified using…

+

Specify a set point for axes spacing

Toggle “no caption” on or off

+

Remove all streams from the WaveViewwindow

+

Sets the offsets all streams to zero. This may make some or all traces move vertically outside of their lanes or even outside of the WaveView window.

15.2.2 Shortcuts for the selected stream

There are also shortcuts which affect only the stream containing the mouse pointer. These are equivalent to the stream actions on the context-sensitive menu.

Remove the active stream from the WaveViewwindow

Display the Colour selection dialogue box for the active stream

Toggles on or off the Details window for the active stream

Null the offset of the active stream in the WaveViewwindow, so that the mean value is centred vertically in its lane

Scale the active stream

+

Scale all other streams to have the same (visual) peak-to-peak amplitude as the active stream

Sets the scale to unity (i.e. display the amplitude in counts)

Sets the offset of the current stream to zero. This may make the trace move vertically outside of its lane or even outside of the WaveView window

Toggle on or off the spectrogram display for the active stream

Increase the colour brightness of the active stream's spectrogram

Decrease the colour brightness of the active stream's spectrogram

15.3 Details window

The following shortcuts are active when the Details window has focus.

Increase the stream's offset by one pixel (regardless of any scaling on the stream)

Decrease the stream's offset by one pixel

Increase the stream's offset by the width of one lane

Decrease the stream's offset by the width of one lane

Null the offset of the associated stream, so that the mean value is centred vertically in its lane
